RANGE-STOVE.

ll'CIE-ICATION forming part of Letters Patent No. 307,804, dated November 1l, 1884. Application tled August 5, 1852. (Xo model.) Patented in Canada October 31, 1881, No. 13,617.

To @ZZ- whom t may concern,.-

Be it known that I, JOSEPH ROY, of the city of Montreal, in the Province of Quebec, inthe Dominion of Canada, have invented certain new and useful Improvements in Range-Stoves; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention has for its object to combine in a range-stove two furnaces, two double ovens, asingle oven,and ahot-water-cireulating boilerl in such a manner that one furnace can be used to heat the double ovens and the other furnace to heat the single oven and the hot-water-circulating boiler, the smoke passing from the range through apertures in its bottom into an underground smoke-duct, the whole forming a rectangular block.

Figure l is a front elevation of my improved range-stove- Fig. 2 is a top View, a portion of the top broken away to show the draft-currents by arrows. Fig. 3 is a horizontal sec tion on line y y, Fig. l. Fig. et is a like section on line a', Fig. l. Fig. 5 is a vertical section on line w w, Fig. 2. Fig. 6 is a perspective view of the hot-water section of the stove, a portion ofthe outer wall broken away to show the dues and position of the boiler. Fig. 7 is a vertical section ofthe range on line o t, Fig. 2.

A is a furnace; B the top of the range provided with pot-holes, and G G are respectively upper and lower ovens.

B is a smoke-passage passing from furnace A laterally and entering over oven G.

C is a detlector between the top plate, B, and top a of oven G,to distribute the heat and smoke,and forms a throat in which is a damper, E, to adiVing-flue, D, which descends totop b of lower oven, G', separated from the bottom of oven G by a horizontal flue-space, d, in which is a detlector, C', to distribute the heat and smoke between the ovens G G. The smoke, after entering between the ovens, passes around the end of detlector C into a diving-flue, D,

which descends to the bottom plate of therange, from which the lower oven is elevated to form a flue-space, e, in which is a deflector, G2, around the end of which the smoke and heat pass into a diagonal duct, 22, and thence through an aperture, 5, in the bottom of the range into an underground duct, 23, and thence into chimney H.

J is a dead-air space between the side of the ovens G G and the furnace A, (of which fis the ash-pia) to prevent direct heat, and I is a dead-air space on the opposite side of the ovens to protect them from direct external cold.

g are dead-air spaces corresponding to the thicknesses of the diving-dues.

On the opposite side of furnace A are respectively upper and lower' ovens, G2 G3, and B2 isthe smokepassage entering over the top a of oven G2.

Gis a deflector between the top plate, B, of the range and top of oven G2, to distribute the heat and smoke, and forms a throat in which is a damper, E, to a diving-flue, D?, descending to top b of lower oven, G3, separated from bottom of ovenG2 by a flue-space, d', in which is a deflector, 0*. The smoke, af ter entering said space between the ovens, passes around the end of deflector GL into a diving-fine, D, which descends to the bottom plate of the range, from which thelower oven is elevated, and forms a flue-space, c, in which is a detlector, C, around which the smoke passes into a diagonal duct, 22, which joins with a duct, 17, hereinafter referred to, and thence through aperture 5 in the bottom of the range, into the underground duct 23, and thence into chimney H.

J is a dead-air space between the side of ovens G2 G3 and furnace A to prevent direct heat, and I is a dead-air space on the opposite side of the ovens to protect them from external cold.

h are dead-air spaces outside the dues at the bottom of the range.

A is a furnace at the rear of furnace A, the backs of the two furnaces separated by the dead-air space g corresponding to the depth of the diving-fines.

f is the ash-pit of furnace A.

3 is a single oven on one side of furnace A', and corresponds in height to the two ovens G G.

B3 is a smoke-passage laterally from furnace A and entering over top t' of oven 3.

C6 is a detlector between the top of oven 3 and top plate, B, of the range to distribute heat and smoke over the top of the oven, and to form a throat in which is a damper, E2, to diving-flue D, which is common to both fur IOO naces. The smoke passes down flue D, thence l between ovens G G', thence into fiue D', thence under the bottom of oven G', thence under the bottom of oven 3, through duct 22 to heat the oven, and thence through aperture 5 into the underground duct 23 leading to chimney H.

J2 is a dead-air space between furnace A' and oven 3 to prevent direct heat, and I2 is a dead-air space on one side of oven 3 to protect it from direct external cold.

S2 S2 are vertically-hung doors of oven 3.

At the side of furnace A', opposite to oven 3, is adead-air space, J3, and within a rectangular walled division of the range is a hot-watercirculating boiler, 4,which is supported ou two walls of a lining, 16. Over the boiler is a plate, 25, bearing on top of lining 16, which is sunk below the top plate, B, of the range to form a smoke-flue, k, which is contracted at the cntrauce and exit by two curved walls, 26, and divided atthe entrance by a deflector, 27, to divert the smoke to opposite sides of the dome. Plate 25 over the boiler has an aperture, 7, at one end, through which rises' the upper end of a vertical hue-plate, I9,which at the lower end is bifurcated to connect the two walls of lining 16 and divide the space between the end of the boiler and wall of the range into two flues leading into two return-fines, 2S, formed by the longitudinal sides of the boiler and lining 16. At the opposite end the boiler is shorter than the lining, to allow the smoke to pass downward between the end of the boiler and division-wall m of the range into horizontal return-flue 8 under the boiler, and below flue 8 is a horizontal return-flue, 17, formed by the walls of the lining 16, and a horizontal division-plate, 9, said iiue 17 leading to aperture 5', through which the smoke passes into underground duct 23 to chimney I'I.

18 is a damper in flue 17, to be closed when the boiler is not required to be heated. By closing dampers 18 and E, when furnace Ais not used, all the heat from furnace A' will pass over oven 3, thence downwardly and between ovens G G', thence downwardly and under ovens G' and 3, by duct 22, into the chimney.

lt are dampers in the oven-walls ofthe deadair spaces J J' J", to admit hot air from the spaces into ovens G, G2, and 3 when desired. rIhe door of the upper and 'lower ovens is hung to fall horizontally, and is supported in a shelf position by quadrantrods 20, one end secured to near the outer corners of the door, and passed through the wall of the range into spaces I J I' J', where their ends are provided with a counterbalanceweight, 21, to stop against the wall to sustain the door when open and to retain it closed when shut.

R' is a header-pipe connected to boiler etby pipe R2, and R" are the distributing-pipes of the hot-water system to heat the building in which the range is placed, S being the returnpipes ofthe system entering the tubular header S', connecting with the dome of the boiler.

P is a hand-rail around the top edge of the range, and Q are doors to allow accumulated soot and ashes to be raked from under and between the ovens.

I claim as my inventionl. A range-stove in which are combined two double ovens, G G and G2 G3, intermediate furnace, A, single oven 3, a hotwater-cireulating boiler, 4L, and intermediate furnace, A', arranged to form a rectangular block, the ovens G G' separated from oven 3 by a space in which are diving-fines D D', common to both furnaces, and fine-spaces over, between, and under the ovens G G', and discharging through duct 22, under oven 3, and thence through aperture 5 in the bottom'of the range, whereby furnace A will more or less heat all the ovens when desired independently of the boiler, as set forth.

2. A range-stove in which are combined two double ovens, G G' and G2 G3, common to furnace A, boiler et, and single oven 3, common to furnace A', said ovens and furnaces separated by dead-air spaces g, and divingflues D D' D2 D, discharging between and under the ovens into ducts 21 22, and thence through apertures 5 5' in the bottom of the range, the whole forming a rectangular block, as described.

3. In a range stove in which are combined two double ovens separated by a furnace, A, a single oven, and a hot-water circulating boiler, i, separated by furnace A' and arranged to form a rectangular block, whereby one furnace will heat the two double ovens and the bottom of single oven, and the other furnace the single oven and the hot-water boiler and discharge the smoke through apertures in the bottom of the range, as set forth.

4. In a range-stove iu which are combined two double ovens, asingle oven, allot-watercirculating boiler. and two furnaces, the boiler supported on a lining, 16, and heated by top flues, k, side fines, 2S, and return-iiue 8, under the boiler, and discharging by fiue 17 into aperture 5' in the bottom of the range, as set forth.
